Best for
  • ML engineering teams standardizing pipelines
  • Teams needing infra portability
  • Organizations combining ML and LLM workflows
  • Engineering teams juggling multiple LLM providers
  • Platform teams building an internal AI gateway
  • Startups wanting free multi-model routing
Pros
  • Portable pipelines — same code from local to cloud
  • Apache 2.0 open-source core
  • 60+ integrations across MLOps and LLMOps
  • Built-in experiment tracking and lineage
  • Managed cloud with free tier and collaboration
  • Free, actively maintained open-source core with a large community
  • Supports 100+ providers through one OpenAI-compatible interface
  • Built-in cost tracking, budgets, and virtual keys
  • Load balancing, retries, and fallbacks for reliability
  • Can be fully self-hosted for data control
Cons
  • Requires Python and MLOps familiarity
  • Orchestration abstraction adds a learning curve
  • Not a compute provider — relies on backends
  • Cloud advanced features are paid
  • Smaller mindshare than some incumbents
  • Self-hosting means you own deployment, scaling, and maintenance
  • Advanced governance (SSO, RBAC, audit logs) requires the paid Enterprise tier
  • Enterprise pricing is negotiated and not fully transparent
  • Acting as a proxy adds an operational hop to debug when issues arise
  • Feature breadth can make initial configuration complex
